A random sample of 88 eighth grade students' scores on a national mathematics assessment test has a mean score of 287. This test result prompts a state school administrator to declare that the mean score for the state's eighth graders on this exam is more than 285. Assume that the population standard deviation is 39. At a=0.13, is there enough evidence to support the administrator's claim? Complete parts (a) through (e) (D) ring the standardized test statistic z. Z= (Round to two decimal places as needed.) (c) Find the P-value. P-value=(Round to three decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. O Fail to reject Ho O Reject Ho (e) Interpret your decision in the context of the original claim 4
